Abstract

The invention discloses a low-noise cement pavement fine friction course and a construction method. The low-noise cement pavement fine friction course is prepared by performing two-layer paving on fine aggregate I, fine aggregate II, an epoxy adhesive, a curing agent and a stabilizer in parts by weight. The construction method comprises the following steps: closing a construction section, polishing the old cement pavement, repairing local diseases and cleaning the pavement; uniformly performing in-place mixing on the epoxy adhesive and the curing agent according to the designed ratio by adopting a synchronous chip seal vehicle, respectively performing layered paving on the fine aggregate I and fine aggregate II, rolling for 1-2 times by adopting a pneumatic-tired roller, and forming an epoxy anti-slide thin layer; spraying the stabilizer onto the epoxy anti-slide thin layer by adopting an asphalt distribution truck after the epoxy anti-slide thin layer is consolidated, performing curing molding and quality inspection, and handing over for later use after qualified. The low-noise cement pavement fine friction course disclosed by the invention has the advantages of being excellent innoise reduction and flatness, high in cement pavement affinity, excellent in adhesive property and the like, the surface structure of the old cement pavement can be rapidly repaired, and the pavementskid resistance and road appearance can be improved.

Description

technical field [0001] The invention relates to the related fields of maintenance and repair of cement concrete pavement, in particular to a fine anti-skid wear layer of low-noise and low-noise cement pavement and a construction method. Background technique [0002] Cement concrete pavement is widely used in bridge and tunnel pavement because of its advantages of high strength, good stability and excellent construction environment. However, the macroscopic structure and microscopic texture of the cement concrete pavement are gradually worn away shortly after opening to traffic, and the anti-skid problem of the pavement has become increasingly prominent. Especially, traffic accidents on bridges and tunnels occur frequently, and the driving safety of the cement concrete pavement of bridges and tunnels has attracted much attention. [0003] Aiming at the anti-skid problem of cement concrete pavement of bridges and tunnels, the more commonly used maintenance method is the horizo...
